CAR-BRAKE DEVICE.

SPECIFICATION forming part of Letters Patent No. 653,056, dated July 3, 1900. Application filed November 7 1898. Renewed March 30, 1900- Serial No. 10,848. (No model.)

To all whom it may concern:

Be it known that I, JOHN S. BAKER, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in Car-Brake'Devices, of which the following is a specification.

This invention relates to improvements in car-brake devices for railway-cars, and although specially designed for vestibule-cars it may with equal advantage be used for other kinds of railway-cars, as will hereinafter be more fully shown and described, reference being had to the accompanying drawings, wherein Figure 1 represents a top plan View of the invention. Fig. 2 represents a central longitudinal section on the line 2 2 shown in Fig. 1, and Fig. 3 represents a detail side elevation of the toothed clutches.

Similar letters refer to similar parts whereever they occur on the different parts of the drawings.

In the drawings, A represents the dasher end ofa car orother suitable support, to which the bracket B is secured in any suitable manner. The said bracket besides servingas a support for the gear mechanism, crank-shaft, and upper part of brake-staff also serves as a box or shell for inclosing the working parts of the device and is closed by means of a cap or cover 0, as shown in Figs. 1 and 2, thus preventing dust, dirt, &c., from clogging the gears which form a part of the working mechanism.

D represents a crank or crank-wheel se cured to one end of the shaft E, suitably journaled in bearings in the bracket B, and to said shaft is secured a bevel-pinion F, the teeth of which mesh with the teeth of a bevelgear G, having a sleeve or hollow hub g, which is journaled in a bearing 1), forming a part of the bracket 13, as shown in Fig. 2.

Within the hollow hub g of the bevel-gear G are contained two toothed clutches H and I, the upper one, I-I, being connected to the hollow hub g by means of a pin K, secured to the latter and passing loosely through slots h h in said upper clutch. This construction permits said clutch to yield upwardly, preferably against the influence of a sleeve g audits gear G from moving upward when the crank-wheel D is turned in an opposite direction to that in which it is turned for Setting the brake.

"The brakebea'msand shoes are connected in a suitable manner to the lower end of the brake-staff M; but as such connecting mechanism is well known in devices of this kind it is not represented in the drawings.

. The operation is as follows: Normally the clutch H is held interlocked with the clutch I by the spring L or by gravity, as shown in Figs. 1 and 3. In setting the brake the operator first turns the wheel or crank D to the right in the direction of arrow shown in Fig.1, causing the beveled pinion F to be correspondingly rotated ,7 and through said pinion'causing a rotary motion to be imparted to the gearG, the interlocked clutches H I, and the brake-staff M. After the slack of the brake has thus been taken up the operator continues to set the brake by rocking the hand wheel or crank D, thus alternately releasing the clutch II from the clutch I and interlocking the same until the desired frictional pressure on the brake is obtained.

During the setting of the brake the brakestaff is held in position preferably by means of the usual ratchet-and-pawl mechanism common in brake devices.

Having thus fully described the nature, construction, and operation of my invention, I wish to secure by Letters Patent", and claim In brake-operating mechanism, the combination with a bracket secured to a stationary part of a vehicle, and provided withvertical and horizontal. bearings, of a shaft rotatably. mounted in the horizontal bearings of said bracket and provided with operating means mounted in the vertical bearings of said for the purpose set forth.

BAKER.
